Head blower fan (HBF) and LED air filter
The head blower fan has the role of sending air through the duct inserted
between the main charger and LED head, to prevent particles such as toner
from adhering to the head. A filter is attached to the intake, to prevent dust
from clogging the duct's draft hole.
1. Disconnect the fan connector from the main unit.
